Abstract

Miscibility between poly(butylene succinate) [PBS], a semi-crystalline polymer with a
natural gum extracted from the pine tree (Pinus Caribaea – Hondurensis), was investigated in
solution cast blends using Differential Scanning Calorimetry [DSC] and Fourier Transform Infrared
Spectroscopy [FTIR]. The spherulite morphology of PBS in the blends was observed with polarized
optical microscopy [POM]. Depression in the equilibrium melting temperature of PBS in the blends
was determined using the Hoffman-Weeks plot method. The depression in the crystallization
temperature of the blends with increasing pine gum ratio and the emergence of extinction rings in
the spherulites of the blends confirmed the blends to be miscible at the molecular level. Infrared
spectroscopy indicated that interactions occurred between the hydroxyl groups of the pine-gum and
the carbonyl group of PBS.
